Instance Method Details

#bundle_exec_command(cmd, path: nil) ⇒ String+

Transform a command to run under bundle exec with the same semantics as Ruby execution elsewhere in this system. That means you should end up with something like /bin/ruby /bin/bundle exec /bin/ruby /bin/cmd args.

Parameters:

  • cmd (String, Array<String>) —

    Command to transform.

  • path (String) (defaults to: nil) —

    Optional input path for command resolution.

Returns:

  • (String, Array<String>)

Since:

  • 2.1.0
